To all wkomrlt may mm.- v i Be it'known that I. EMIL C. SIX'rA a citizenof the United States, residing at.

Cleveland, in the county of Cuyahoga and State of Ohio, have inventedcertain new and useful lmprovements in Building Blocks, ofwhich thefollowing is aspecification. p

M invention relates to improvements in building blocks, andmoreparticularly to. that class or type. which are adapted to interlock witheach other-when theblocks are laid or set up in the completed structure;

The primary object is to provide agenf provision of a series of blocksof anovel.

construction which may be joined together in various ways to producedifferent kinds of building structures and which may be arranged indifferent ways in the same structure to vary the ornamental appearancethereof.

A still further object is the provision of novel interlocking meansrequiring the blocks to be laid or set up in a novel manner, so thatwhen the structure is completed the samemay be lifted up and moved fromone position to the other without breaking up or disarranging the blocksor units and when it is desired to teardown the same requiring that theblocks be removed in substantially reverse order to the building up ofthe same in the original structure.

With the above mentioned' and otherends in view, the invention consistsinthe novel construction, arrangement, and combination of parts,illustrated in", some of its. embodiments in the accompanying.drawings,-and

particularly pointed out in. the appended claims.

Referring to the p 01" this speclficatlon, Figure 1 1s a Irontelevationof a building builtup witlrmy improved interlocking blocks .or units.

Upon reference to the drawings, it wlllbe seen that the buildingstructure is made up a of 'a plurality of blocks or units suitablyarranged and interlocking, as hereinafter described. I The variousbuilding blocks or units may be of any suitable and convenient materialandxlikewise of any suitable and convenient .form. For example, certainblocks may take thespecific form or suitably ornamented base blocks 1,to form the initially laid base or foundation of the structure andsuitable cornice forming blocks 2,

the windows being formed by means of side bar formingblocksB', adaptedto interlock with suitable projections or tenons 4 and 4 of thetransverse frame forming blocks l. In the present instance, the basewindow block l is provided with subjacent hook shaped projections 4(corresponding to the hooked projections on the regular blocks orunitshereinafter described) adapted to interlock with the flangedrecesses of the subjacent regular blocks or units 5.

It will be seen that. each block {or unit 1, 2;: or 5 is "provided-withoppositelyarrange'd recesses and projections adapted to receive andinterlock with the corresponding'projec y tions and recesses ofsuperposed and subjacent blocks, respectively, when set .llpl' ifilcorner flanges or projectionse As a means of interlocking a"superposedblockor unit with theundercut projections 5 of the sub j acent units,eachu'nit'or block is provided with depending"projections 5, said projec tions 5, inthe present instance, being spaced apart to fornranintervening tenon receiv= ing recess'5 'fa-nd being provided withhorizontally extending orojections 5 adapted to enter beneaththeprojections'5 of aipair' ot' subjacent blocks when-laid, as shown mostclearly in Fig. 4 of the drawings. It will'thus be noted that the parts5" and 5 of the --proj ections form substantially hook shapedprojections facing towards the outer sides or the wall and thatfindayingup the blocks each block to be placed in position will be initiallyplacedsliglrtly 'to the rear of the subjacent blocks and moved forwardlywith the front edge thereof flush' with the two subjacent blocks,therebycarrying the ton ues orfree ends of the hooks'5 beneath thecornerprojections 5 of thesubjacent blocks. Upon reference to Figs. 2, 7 and'8 of the drawingsitwill'be seenthat the cornice-block 2 lacks the undercut recesses 5, 5" and projections5 tormed'in the top portions ot'theregular blocksbut is providecl with the corresponding hook shapedportions 2 and 2 with the tenon receiving recess 2 Upon reference toFig. 5 it willbe seen, on the other hand, thatthe base 'block 1, lacksthe depending ,hook shaped projec tions but'isjprovided'with a mainrecess and second'recess 1 forming corner projections 1,"andcorresponding to the partso 5 and 5 ofthe'regu'lar blocks." Similarremarks apply to the transversewindow or door frame blocks 4, it .beingnotedthat the upper block 4 is provided with a mainiunder cut'rece ss 4and a second or smaller recess i forming the undercut corner projections4L, and in this connectionit will also be noted thatthe blocks 4L areprovided with tenons, adapted toenter into recesses or mortise openings3, in the side bar forming blocks 3. The'side'bar forming. blocks 3 maybe provided withrecessesfi on their'inner sides to receive thesashframes and by the use of the drawings, such blocks 3 may be ex tended toform the side bars of the door framesar Somewhat similarly Lshaped barforming blocks 7 provided "with grooves 7*,

may be used in forming partition wall supl porting bars and-horizontalfloor supporting bars or joists, as shown in Fig. 7 of the drawings Insuch instance it will be also seen that iiller blocks 6, such as shownin Figs:'10 and 11-, areutilized in forming the joints or connectionsbetween the vertical horizontally extending wall supporting barsorfbeams and that similarly shaped filler, blocks may be us'ed in makingdesired lengthsorextensionsof such beams, the

'filleribl'ock's" 6 being provided with, tenons 6*, adapted to enterinto mortise openings,

in the adjacent blocks to be supported.

Referring to Fig. 8 of the drawings, it

will be seen that root or rafter forming blocks 8, are provided, saidblocks 8 being provided'with roof. or board receivingrecesses 8,1nthe1rsides and being'provlded j at their endswith mortise openings 8 to receive tenons 9 and 10, of key forming blocks provided with tenons 10",adapted 'to enter Having thus described some of the embodiments of myinvention, without having I attempted to setforth all the forms in whichit may be made,"or all the modes of its use, what I claim and desire [tosecure by Letters Patent, is,-

A. building block having mainand supplemental recesses on its top extending from the rear thereof andforming corner projections, said block being provided on its lower sidewith spacedhook shaped projections extending towards the face of theblock to enter into the recesses of a subjacent block from the rearthereof and to interlock with said corner projections when in place.

15. A buildingblock having undercut recesses and projections on its topand under sides to receive and interlock with corresponding undercutprojections and recesses of superposed and subjacent blocks,respectively, said undercut recesses and pro ections being spaced apartto form mortise recesses between theblocks on the inner sides thereoffor tenons of adjacent blocks.

7 l6. Abuilding block having main and supplemental recesses on its topextending from the rear side thereof and forming overhanging cornerprojections; said block being provided on its lower side with spacedhook shaped projections extending towards the face of the block to enterinto the recess of a subjacent block from the rear thereof and tointerlock with said corner projections. when in place.

17. A building block having undercut recesses and projections on itstopand under sides to receive and interlock with corresponding undercutprojectionsand recesses ofsuperposed and subja cent blocks, respectivelysaid undercut recesses forming spaced projections to receive andinterlock with projections of a superposed block and said projectionsbeing spaced to form mortises to receive tenons of adjacent blocks.

In testimony whereof I have affixed my signature.
